To all wlwm. 'it may concern Be it known that I, Ennis Bmmooons, citizen of the United States', residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Motor- Oars, of which the following is a specification.

This invention relatesl to out-board motors.

The primary object of the present invention is, in a ready, novel and practical manner, to utilize the motion of the propeller shaft when driven `in either direction, to actuate a force pump for supplying water continuously, while the propeller is'revolving, to the water jacket of the engine whence it is discharged into an out-take communicating with the exhaust, the action of the water in conjunction with the spentgas from the cylinder operating to set upa partial vacuum in the exhaust, which will operate eiectively to scavenge the cylinder and thus maintain the engine in the best condition for doing effective work.

A further object is to' improve the manner of combining the yrudder with the rudder post whereby the latter may readily be removed or replaced, as the requirement may arise without disturbing any of the parts of the steering mechanism.

A further object is to improve the manner" of combining the motor with a boat whereby to permit any adjustment ofthe rudder post, the rudder and propeller, in aV manner'that may be accomphshed merely by the adjustment of a single part of the attachment.

A further object is to improve the c'o'nstruction of the mixing valve in such manner as to insure positive andV thorough mixing of the air and hydro-carbon pa'ing to the cylinder, whereby to conserve the gasolesion.l

` With the above and other objects 1n view, as will appear asV the nature of the invention is better understood, theA same' consists, under -he'iirst object stated, in wi the propeller shaft a. force piuhand concasing with lthe water being of the force' type er t e of the' propeller,

the

where y un to the jackets, and is condncted'thenee' to a' pipe connecting the exhaust, the water conducting Hte short of the lower endo the out-take p1 whereby a'sl the spent gases escape `thus maintain the same in the best the out-take pipe, they are met by the water escaping from the jacket and the two agents in theirpa'ssage through the out-take estab- 'lisli a partial vacuum, which serves to opcrate upon the cylinder inv such manner as to scavenge the same of all burnt gases and possible shape for doing effective work. The object stated under the second head consists in mounting upon the rudder post a casting having two arms each'provided with a longitudinal slot, and a'rudder blade havin a longitudinal slot, bolts being employe that project throu h the slots and through Athe rudder blade, t e nuts of which, upon being loosened, will permit of the head of the bolt or of the nut that clamps they casting to the blade to pass through the longitudinal slot in the latter, and thus permit the blade readily to be detached from the casting.

The object stated under the third head i consists in providing the clamp' that secures the engine and its attachment to the boat, with a segmental arm, and further employ- Ying a brace bar', the upper end of which is pivotally connte'd with a boss carried by the upper portion of the clamp, and the lower end of which is pivotally-connected with a. sleeve mounted upon the rudder post, the brace bar adjacent to its lower end being provided with a clamp arranged to slide upon the segmental arm, and be held in any desired adjustment thereof by means of a set screw carried by the clamp and co-acting The object stated under the fourth head in providing the mixing valve with a series of orifices, forming thereb a screenlike' bottoni upon which the gaso ene drpping" roln' thevalve seat Spread, thus peran intimate mixture oaf the air and the passes to the cy r.

invention consists in various other novel detailsy of hereinafter and claimed.

In the accompanying drawings fg" Ek e part of specification, and in whichv reference indicate corresponda'constant stream of water beisuppliedf ing the' motor engine Fig. 3 is an enlarged detail sectional view showing the manner in which the water from the water jacket is conveyed to the outlet that communicates with the exhaust, whereby to set up a partial vacuum in the latter. Fig. 4 is a plan view showing the novel form of steering ring employed, and the manner in which` the latter operates to actuate the rudder. Fig. 5 is a view in front elevation of the force pump used in supplying water to the water jacket of the motor. Fig. 6 is a 'vertical longitudinal sectional view through the drive shaft head. Fig. 7 is a. horizontal sectional view taken on the line 7-7, Fig. 6. 8 is a sectional detail view showing the arrangement of the gearing for driving the propeller and also the means for operating the pumpfor supplying water to cool the jacket of the cylinder. Fig. 9 is an enlarged detail view inA front elevation of the boat clamp. Fig. 10

Y is a vertical sectional view through the carbureter, and, Fig. 11 is a horizontal sectional view taken on the line 11-11, Fig. 10.

Referring to the drawings, C designates the cylinder of the gasolene motor provided with the usual water jacket J, S, the steering wheel, and E, the exhaust, and as these parts may be of the usual or any preferred construction, further description thereof is deemed unnecessary.

The engine as a whole is suspended from the stern of a boat B by a clamp that is provided at its upper end with two arms 1 and 2 that straddle the castin of the engine and are held pivotally assem led therewith by a bolt 3. The clamp has integrally formed with it a relatively long arm 4 and a relatively short arm 5, the former being designed to bear against the outer surface of the stern of the boat and being provided at v its lower end with an upwardly curved segmental arm 6, the arm 5 terminating in an internally threaded head 7 carrying av clamp# ing bolt 8 that is designed to secure the clamp as a whole to the upper edge of the stern. With the engine and its accessories moving upon the bolt 3`as a pivot, it is necessary that some means must be employed whereby theengine shall be maintained in any desired angular adjustment, thus to in-l sure the most effective working of the propellery and Voperation of the rudder. T 0 secure this result, there is a brace bar 9 em- 5 5 ployed, the upper end of vwhich is pivotally connected with a pair of lugs 10 projecting outwardl from the upper portion of the arm 4 o the clamp, the lower end of the bar being pivotally connected with an exten- 00 sion 11 carried by a collar 12--slidably mounted upon' the rudder post 13.- Adjacent to the` lower end of the brace bar is arranged a collar 14 that is designed to slide upon the arm 6, and tobe held at any desired-adjust- 05 ment relatively thereto by aset screw or bolt 15, clearly shown in Fig. 1. From this ar rangement, it will be seen that should it be desired to alter the angular adjustment of the engine with relation to the stern o the boat, it will only be necessary to loosen the set bolt 15, swing the structure bodily to the desired angle, and then re-tighten the bolt l5.

The rudder post 13 to which reference has been made comprises two tubular members 16 and 17 having telescoped relation, the upper end of the section 17 having combined with it a split collar 18 provided with ears 19 through. which passes a clamping bolt 20, the object of this arrangement being to permit of any adjustment of the parts, and their rigid securing together when the adjustment has been completed. The section 16 of the steering post is rigidly connested with a spiral 21 secured to the under side ofthe enginefcasing, and carries a col lar 22 that is held assembled with the section by a screw 23, the collar having an arm 24 projecting from it in which is mounted in any suitable manner, the steering post 25.

The vcasting designated by numeral 25 is right angular in shape, as shown in Fig. 6. Its vertical portion is provided with a square hole for telescoping with member 27. Tiller handle 26 isa detachable handle adapted to be fastened to the horizontal portion of member 25 in a suitable manner. Telescoped within the member is the steering rod 27, the two parte being held at the desired longitudinal adjustment by a set bolt 28. Loosely disposed adjacent to the lower end of the rudder post is a steering ring 29 shown in detail in Fig. 4, this ring being free from contact with the rudder post. On one side of the ring is a boss 30 in which is rigidly secured the lower portion of the member 27 of the steering post, its lower terminal being stepped or seated in an extension 31 of a collar 32 secured adjacent to the lower end of the section 17 of the rudder post by a screw 33. In diametrical alinement with the center of the-boss30 is a slot 34 in which works a stud or pin 35 depending from the lower side of the rudder supporting casting. This casting, as shown in Fig. 2, consists of two collars 36 encircling the section 17 of the rudder post and forming a continuation of two arms 38, connected by a bend 39, each of the arms being provided with a suitable longitudinal slot 40.

As above'stated, it is one 'of the objects of the .invention to assemble the rudder' with the rudder post in such manner as to permit ofthe former being readily detached and adjacent to its upper endwith a key-hole shaped slot 43, asushown. The notches are engaged by`bolts 44 that pass through the 'mascia slot 43. N ow, shOuldvit be desired to move' the rudder, it will simply be necessary to loosen the bolts 46 and 4'( and move the fr0 rudder awayA from the rudder post to permit the head of the bolt 45 to come oppomte thel large end of the. key-hole slot, when, in a manner that will be'obvious, therudder may be detached` Secured to the lower end of the rudder post is a casing 48 in which are disposed the beveled gears 49 .and 50 for imparting motion to the propeller shaft '51, the latter carrying at one end la propeller 52, .of any pre.-

ferred construction, the gearl 49 being carried by the lower end of the drive shaft 53 -which extends upward lthrough the rudder post and is connected in any suitable man# ner with the engine, while the gear 50` is l carried by the propeller shaft 51. Secured to the casing at the end opposite that occupied by the propeller is a casing 54 in which is arranged a force pum intermeshing gears 55 an 56, the former of which is carried by the propeller. shaft 51 and the latter of which is loose in the casing and runsl on the top of the gear 55, and is provided with 'a hole '56 to lighten the structure. The chamber in the casing is of substantially 8-shape, and the propeller or gear `55occupies the lower segment of the casing and practically fills it while the upper propeller or gear 56 occu ies only about `one-half of the upper cham r, as clearly v shown in Fig. 5, and travels back and forth pipe 60, one end of whichv connects with aV in the casing, in accordance with the directionof vthe rotation of the gear 55. The casing i's'provided with a tubular extension 58 to which is connected the lower end of a pipe 59, the upperend of which enters the side of the water jacket, as shown in Fig. 1 Now, it will be-seen that as the propeller is Y driven bythe engine, inthe usual manner,

that the Water entering the pump'chamber will be forced upward therefrom through t pip'e '59 into the waterjacket, whence er circulating inthe usual lmann er,'it escapes from the top of the jacket through a coupling 61 having, threaded. engagement with the water-jacket, land the other end of which connects with one'end ofv a union 62,(

suitable mannerjwith the'exhaust EL As clearly shown in Fig; 3, the union 62,

the Vother end of which is connected in any i', withinlthe exhaust E has connected with it comprising two bring the rudder to the most effective y of a water jacketenginera reversibly oper4fr- A a connection m the pipe 63 and in their passage to- Ward escape, the gas and water cause a partial vacuum to be created in the exhaust which will o crate to withdraw burnt gases from the cylinder, and thus scavenge the latter, thus causing the engine always to be maintained in the best condition for user As usual, the cylinder is provided with a carbureter 67, shown in detail in Fig. 10, in which is arranged a spring seated mixing valve 68. The casing of the carbureter is provided with a chamber 69, the bottom o f which is formed with a series of openings 70, and projecting upward from the bottom is a sleeve71 in which works the stem 72 of the valve 68. Projecting from the casing is an extension4 73 having a threaded bore therein for the reception of' theneedle valve- 74, the extensions being provided with a duct 75 leading from Vthe feed tank. One side of the casingis provided with an extension 76 that connects with the cylinder of the engine.

From the foregoing' description, it will be seen that every provision is made whereby vertical adjustments of the various parts of the steering mechanism may be effected, and further provision is made whereby the engine or structure as a whole may be adjusted relative to the steering of the boat posiloo tion for operation.
